A Node has N keys, and N+1 children. A Leaf has N keys and N children. A key in a Node is just used as a marker, helping the btree to go down to the correct leaf, we just keep the higher key from the right subtree in a node, so that you can know if you have to go down the btree using the left child or the right child, by comparing your key with the key stored in the node. > Some data can be lost when using ldapadd command to insert data into apacheds > ----------------------------------------------------------------------------- > > Key: DIRSERVER-2047 > URL: https://issues.apache.org/jira/browse/DIRSERVER-2047 > Project: Directory ApacheDS > Issue Type: Bug > Components: ldap > Affects Versions: 2.0.0-M19 > Environment: centOS 6.5 with openldap and apacheds installed > Reporter: linzhao > Priority: Blocker > Labels: LDAP > Fix For: 2.0.0-M20 > > Attachments: data.ldif, ordered-data.ldif, site.ldif, site_new.ldif, site_topology_schema.ldif, supercluster_partition.ldif, test.jpg > > > In our system, we need to do data backup and restore for apacheds. For now, we use the ldapsearch and ldapadd command to do BR function. We use ldapsearch to backup apacheds data to be a ldif file and use ldapadd to restore the data. But when the ldif is a little big, I always found that the data can't be restored successfully, but the ladpadd command showed that the data can be added successfully. No exceptions for ldapadd command. But the restored data didn't exist in the node. This bug only happened when the ldif file is a little big. I mean if the data entry greater than 500 entries. But the node for backup and restore is using mavibot partition. Because I found so many problems for jdbm. So I change it to mavibot partition. Another question is that do you know is there some good way to do the data backup and restore for apacheds? > May be my mavibot partition has some problems, so someone can tell me how to create a mavibot partition in APACHEDS? Because the mavibot parttion I created can't be viewed when click the "Open Configuration" in apacheds studio. Also I used unboundid JDK to insert many entries apacheds and the same problem happened. So someone can tell me how to config the mavibot partition on APACHEDS? That's may be very helpful. > Below is the exceptions from apacheds when problems happened: > [16:21:41] INFO [org.apache.directory.server.ldap.LdapServer] - Ldap service stopped. > [16:21:41] WARN [org.apache.directory.server.core.shared.partition.DefaultPartitionNexus] - Failed to flush partition data out. > org.apache.directory.api.ldap.model.exception.LdapOperationErrorException > at org.apache.directory.server.core.partition.impl.btree.AbstractBTreePartition.saveContextCsn(AbstractBTreePartition.java:3364) > at org.apache.directory.server.core.shared.partition.DefaultPartitionNexus.sync(DefaultPartitionNexus.java:319) > at org.apache.directory.server.core.DefaultDirectoryService.shutdown(DefaultDirectoryService.java:1283) > at org.apache.directory.server.ApacheDsService.stop(ApacheDsService.java:600) > at org.apache.directory.server.wrapper.ApacheDsTanukiWrapper.stop(ApacheDsTanukiWrapper.java:97) > at org.tanukisoftware.wrapper.WrapperManager$13.run(WrapperManager.java:3134) > Caused by: java.lang.NullPointerException > at org.apache.directory.server.core.partition.impl.btree.AbstractBTreePartition.saveContextCsn(AbstractBTreePartition.java:3350) > ... 5 more > [16:21:41] ERROR [org.apache.directory.server.wrapper.ApacheDsTanukiWrapper] - Failed to stop the service. > org.apache.directory.api.util.exception.MultiException: ERR_265 Grouping many exceptions on root nexus sync() > at org.apache.directory.server.core.shared.partition.DefaultPartitionNexus.sync(DefaultPartitionNexus.java:328) > at org.apache.directory.server.core.DefaultDirectoryService.shutdown(DefaultDirectoryService.java:1283) > at org.apache.directory.server.ApacheDsService.stop(ApacheDsService.java:600) > at org.apache.directory.server.wrapper.ApacheDsTanukiWrapper.stop(ApacheDsTanukiWrapper.java:97) > at org.tanukisoftware.wrapper.WrapperManager$13.run(WrapperManager.java:3134) > Nested exceptions to follow: > INFO | jvm 1 | 2015/02/02 17:11:06 | [17:11:06] WARN [org.apache.directory.server.ldap.LdapProtocolHandler] - Unexpected exception forcing session to close: sending disconnect notice to client. > INFO | jvm 1 | 2015/02/02 17:11:06 | java.io.IOException: Connection reset by peer > INFO | jvm 1 | 2015/02/02 17:11:06 | at sun.nio.ch.FileDispatcherImpl.read0(Native Method) > INFO | jvm 1 | 2015/02/02 17:11:06 | at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:39) > INFO | jvm 1 | 2015/02/02 17:11:06 | at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:223) > INFO | jvm 1 | 2015/02/02 17:11:06 | at sun.nio.ch.IOUtil.read(IOUtil.java:197) > INFO | jvm 1 | 2015/02/02 17:11:06 | at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:379) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.transport.socket.nio.NioProcessor.read(NioProcessor.java:311) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.transport.socket.nio.NioProcessor.read(NioProcessor.java:45) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.core.polling.AbstractPollingIoProcessor.read(AbstractPollingIoProcessor.java:694) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.core.polling.AbstractPollingIoProcessor.process(AbstractPollingIoProcessor.java:668) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.core.polling.AbstractPollingIoProcessor.process(AbstractPollingIoProcessor.java:657) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.core.polling.AbstractPollingIoProcessor.access$600(AbstractPollingIoProcessor.java:67) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.core.polling.AbstractPollingIoProcessor$Processor.run(AbstractPollingIoProcessor.java:1121) > INFO | jvm 1 | 2015/02/02 17:11:06 | at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.java:64) > INFO | jvm 1 | 2015/02/02 17:11:06 | at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > INFO | jvm 1 | 2015/02/02 17:11:06 | at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > INFO | jvm 1 | 2015/02/02 17:11:06 | at java.lang.Thread.run(Thread.java:745) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
